Small and Medium-sized Seawater Desalination Technology

Integrated seawater desalination technology can meet the demand for fresh water in various industries at sea with a scale below 1000m³/d. It adopts the reverse osmosis membrane seawater desalination process and can be coupled with renewable energy to achieve stable operation matching solar energy, wind energy, and other renewable energy sources. The integrated seawater desalination technology features short process, low energy consumption, green process, modularization, and lightweight. It has formed a series of application demonstrations in ocean-going fishing vessels, some islands and reefs in the South China Sea, Changdao in Shandong, Zhoushan in Zhejiang, Zhuhai in Guangzhou, and other islands and coastal areas.

Application fields

(1) It can provide domestic and production water for ships, offshore platforms, offshore pastures, and other fields.

(2) It can provide fresh water replenishment for the domestic, production, and construction water needs of island and coastal residents.

(3) It can provide complete fresh water guarantee for remote islands without electricity and coastal areas.

Technical Advantages

(1) The device adopts one-button start and stop, realizing intelligent operation.

(2) Equipped with a self-developed energy recovery device, it has lower energy consumption and higher stability.

(3) Adopting integrated and modular design, it occupies less space and can easily realize maintenance and replacement of key components.

(4) Coupled with renewable energy process design, it realizes stable operation matching solar energy, wind energy, and other renewable energy sources.
